Do you grow your Arum creticum and concinatum outdoors?

Dear all;
A little mentioned genus on this forum is Arum. In the last few years I have grown increasingly fond of the species and have been slowly expanding my collection. A few recent additions have invigorated me to drop this note. The literature suggests that most of the species are somewhat tender, but I have had success with Arum italicum and maculatum (who hasn't?) but also A. dioscoridis, A elongatum, A. nigrum and more recently with a few others. I also grow a couple more tender species in a cold green house- A. concinnatum, A purpureospathum etc.

Dr. Peter Boyce has produced an excellent starting point for discussions here with his book 'The Genus Arum'. Thanks again, Pete.

I'd like to hear of others with hardiness experience and a willingness to trade.

I currently have a few extra tubers of A concinnatum (small), A byzantinum (few) and one or two others.

I'd like to get other potentially hardy species (such as A. alpinum, creticum, korolkowii etc.) or selected forms of any of those mentioned earlier, such as A. maculatum 'Painted Lady', etc.

These are mostly just going dormant and making seed heads now. A good time to dig, divide, trade etc.

Anyone have 2 cents to add for this Arumophile?

Thanks Jim W.

You might try your quest for Arum on Arisaema-L. Berndt Peters has
the most extensive Arum collection I know of and he's usually interested
in trading.

I agree! Arums certainly aren't getting the
attention they deserve! I've been growing
several species here in Raleigh, NC, USA (USDA
Zone 7) with very good success.
From late Fall to early Spring, they are the only
cold hardy aroids, other than the
infamous skunk cabbages, that can remind
aroid-fanatics of how great this plant
family is.

Like Jim Waddick, I'm a great fan of arums, though it must be admitted
that their inflorescences are, to put it nicely, short-lived. On the
other hand, their smell is not, to me, nearly as bad as some writers
imply - but then, I do have allergies.

I can't add anything useful on hardiness, but I do want to mention that
I was thrilled with the inflorescence on Arum orientale ssp. sintenisii,
whcih finally bloomed this year (Berndt Peters generously shared it with
me many years ago, and it has multiplied like crazy ever since, but never
reached blooming size). It is every bit as pretty as it looks in Peter
Boyce's book: elegant satiny maroon-crimson spathes held above the
foliage, and it really does smell good.

I am puzzled, however, to see that A. orientale ssp. sintenisii, on casual
inspection, has much more in common with A. elongatum (also a satiny
red-maroon, but with a white "flare" up the middle) than it does with
A. orientale ssp. orientale, where the spathe is more "boat-shaped" (broad
and open) and purplish. The foliage of the first two is fairly
similar, though A. elongatum holds its flowers lower in its leaves (among
them) - as does A. orientale subsp. orientale. I know all three are
pretty closely related, and I believe the IDs are correct. Thoughts from
my betters?

Yes, but how can a tetraploid plant set seeds?! If meiosis
occures the chromosomes cannot be "halved" correctly by pulling threads, so I
think it could not bear living pollen or oocytes, but my plants sets seeds
